Is it too late for me??

FTM here to a lovely little boy (3.5months) and I'm getting nervous about formula shortages in the area I live in, so I'm hoping to kickstart my breastfeeding journey again, even though it came to an end a month ago due to unfortunate circumstances. I wasn't ready to give it up, and want to try again. I'm still able to manually express some drops, as well I can pump a few drops

I haven't BF or pumped since then, so I'm wondering if it's the end for me.. any advice welcome!!
